Original 1982 copies were available with a picture sleeve while the October 1984 re-release featured a Classic Cuts sleeve as it was part of Phonogram's Classic Cuts campaign. Some copies in the 1984 campaign however still had original picture sleeves. All the 1984 pressings were silver inkjet moulded labels.
Since everyone's listing their first injection moulded labels, here are mine! I was only born in 1979 though... and this was actually my brother's.
Anyway, I think these Mercury labels were later in the run and only came in the red and black phonogram bags (this one did and the only other ones I've seen were also in company bags). I think this one came from a supermarket that usually sold ex jukebox singles... perhaps they over-pressed and sold them off cheap...?
